The room was definitely very clean. You might even say crisp, like freshly laundered linen. If I had to make one quibble, it would be that the weatherstripping at the bottom of the shower door was not watertight; we found that we needed to avoid letting water splash on the door, in order to minimize the amount of water found on the tile floor on the by the toilet.
While not large and spacious, we found the room to be satisfactory for our needs; not the least bit cramped.
The free Wi-Fi was disappointingly slow and laggy; in this day and age, having free vs fee-based tiers makes as much sense as having lukewarm shower water for free and hot water for those willing to pay extra.
The breakfast offerings were quite generous and diverse. And being able to have espresso was a very welcome thing. Somewhat related, I was happy that there were 2 espresso machines; it seemed one of them was in maintenance mode one morning, so it was great that there was still an option for espresso/cappuccino/etc. Regrettably, we didn't take the opportunity to try the evening restaurant offerings, although we did retire to the lounge for drinks a couple of evenings there.
For anyone curious, the nearest streetcar stop seems to be the Marktplatz station, which is about a 10 minute walk from the hotel. For those unfamiliar, we used the DB Next (Deutsche Bahn) app to order and use tickets for streetcars and trains on a daily basis there. Highly recommend.
